+ *        use osmo_timer_schedule to schedule a timer in

+ *      - Use osmo_timer_del to remove the timer
+ *
+ *  Internally:
+ *      - We hook into select.c to give a timeval of the
+ *        nearest timer. On already passed timers we give
+ *        it a 0 to immediately fire after the select
+ *      - osmo_timers_update will call the callbacks and remove
+ *        the timers.
